FOLDING UMBRELLA.

Application filed. April 28,

To all 107mm it may concern Be it known that I, ldonnis H. HAnrznLL, acitizen of the United tates. residing in the city and county ofPhiladelphia. State of 6 Pennsylvania. have invented a new and usefulFolding Umbrella. of which the following is a specification.

My invention relates to an umbrella or parasol that may be folded. andconsists in forming the ribs thereof in sections. and novel mechanism atthe joints of the latter whereby said joints are strong" in their natureand serve to prevent the sections from twisting; or torsion at saidjoints. and serve also to guide the 'loidinn sections in their folding;and unfoldin r motions on the sections that are pivotally connected withthe notched collar on the upper end of the stick.

lhe invention is satisfactorily illustrated in the accompanying drawing,but the important instrumentalities thereof may be varied. and-so it isto be understood that the invention is not limited to the specificdetails shown and described. as long as they are within the spirit orscope of the claim.

Figure 1 represents a side elevation of a portion of the frame of anumbrella in open condition.

Figure 2 represents a side elevation of a portion of the frame in foldedcondition.

Figure 3 represents a side elevation of portions of members shown inFigure 2 on an enlarged scale.

Figures 4- and 5 represent longitudinal sections respectively. .at aright angle to each other of the foldable joint of the sections of theribs.

Figures (3 and 7 represent perspective v'ews of detached members of thejoint.

Figure 8 represents a section of a portion of a modification.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings.

e5 1 designates the stick of the umbrella, the same being formed ofsections 2 and 3, the adjacent ends of which are adapted to be connectedas one by the catch 4 which when the umbrella is to be formed in folded,con

dition is adapted to be operated to disconnect said sections to admitthem to be folded together in the folded condition of the umbrella. v

5 designates the ribs of the umbrella each as of the same being formedof sections 6 and 1922. Serial no. 557,168.

7, the adjacent ends of which are connected as one by the pivot 8whereby the sections may be continuous in the normal condition of therib as in Figure 1, or folded as in Figures 2 and 3.

The sections 7 may be termed the folding sections, while the sections 6may be termed the fixed sections, which latter are connected with thenotched collar on the stick as usual. To the adjacent ends of a rib aresecured the sleeves 9 and 10 respectively. the same being connected bythe pivot 8 as above. -Portions of the sides 11 of the pivotal end ofthe sleeve 10 are brought together forming between them the channel 12and portions of the sides 13 of the sleeve 9 are spread apart to receivebetween them the portions of the sides 11 of the sleeve 10, the pivot 8being passed through said sides 11 and 13 thus forming the axis of saidsleeves and consequently the joint of the sections of the rib.

l-i designates a radial or swinging arm composed of a plate, a portionof which freely enters the channel 12 of the sleeve 10 and has the endthereof mounted on the sides 11 of said portion by the pivot 15 wherebysaid arm may turn in said sides and consequently on the sleeve 10, andthe opposite portion freely enters the channel 16 in the sleeve 9between the spread apart sides 13 thereof.

Connected with the end of said arm 14- opposite to its pivot is one end17 of the coil spring 18, the latter passing the sleeve 9 and extendingalong the adjacent portion of the section 7 of the rib 5 to whichsection the other end of said spring is connected by the clip 20, havinga pin or bar. as in Figures 4, 5, and 8, or other device thereon for thepurpose.

he walls 13 of the collar 9 are inturned as at 21 forming stops for theends of the sleeve 10 against which said end abuts, see Figure 7.

It will now be seen that said spring 18 now exerts its tension on theradial arm. 14 and consequently on the section 7 or the rib whichsection follows said arm and time said section 7 forms continuity of thesection 6 in the normal condition of the umbrella, and so the latter maybe opened and closed as usual.

The stretchers 22 are connected with the sections 6 of the rib as usualin umbrellas. When the umbrella is to be folded, the umbrella beingclosed or partly closed, the sections 7 of the ribs are folded on thesections 6 thereof, the radial arms followi g the pivoted ends of thesections 7 of the ribs and removing from the channels 16 of the sleeve9, thus drawing the springs with them and expanding the latter, as shownin Figures 2 and 3, and the lower portion of the covering of theumbrella is turned over said sections, the sections of the stick beingalso separated and folded and so the umbrella is folded in compactshortened form convenient to be carried, packed in a sa-tchel, suitcase,trunk, etc, wrapped, stored away, etc.

W' hen the umbrella is to be restored to its normal condition, thesections 7 of the rib are drawn outwardly from the sections 6 and. thusmanipulated as to be unfolded. The springs 18 then contract and so exerttheir tension or draft on the radial arm and also on said sections 7when the latter are returned to their normal position closing on thsections (3, and thus restoring the ribs to their normal condition, asin Figure l. The cover also resumes its normal position on the ribs andso the umbrella may be opened and closed as usual.

sections, a resilient member connected toone or sa d sections andadapted to hold said sections as continuities of each other, and aswinging member directly pivoted to the other of the sections of the riband disconnected from the first-named section and having1 said resilientmember connected therewit 1.
